SPBAYiNG MECHANISM FOR COKE OVENS.

Application filed April 23, 1924. Serial No. 708,480.

To all whom it may concern:

Be it known that I, MARIO CARINI, a citizen of the United States, residing at Belle Vernon, in the county of Fayette, and State of Pennsylvania, have invented certain new and useful Improvements in Spraying Mechanism for Coke Ovens, of which the following is a specification.

This invention relates to novel and improved spraying mechanism for coke ovens and is especially designed for use in connection with a single or a plurality of ovens, whereby water is delivered upon the coked material while still hot in the oven in order that said material shall be cooled to a temperature at which it may be safely handled.

The prime object of the invention is to provide simple, durable, eflicient and comparatively economical means for the purpose, said means constituting a labor saving device to such an extent, that one employee can perform the work of three, and at the same time accomplish. the desired purpose more. accurately and thoroughly than it has been done heretofore.

A further object of the invention is to so construct my improved device that the sprinkling means may be automatically shifted into and away from the ovens, and moved from one series of ovens to another series at the will of the operator.

Further and more specific objects of the invention are to provide a motor opera-ted device which shall include means connected herewith adapted to impart a partial rotary movement back and forth to all of the sprinkling pipes simultaneously; mechanism for shifting said means out of gear; means so constructed as to permit the use of the device in connection with a single oven or simultaneously with a series of ovens; and means for reversing the movement of the device both longitudinally and transversely. The foregoing and such other objects as may occur from the ensuing description are accomplished by the combination, arrangement, construction and location of the several parts hereinafter more fully described, illustrated in the accompanying drawings and particularly setforth in the claims appended hereto, it being understood that slight changes in the precise form, proportions and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

, In the accompanying drawings forming a part of this specification it will be seen Figure 4 is a cross-section taken in the plane of the dotted lines 4-4, Fig. 2, looking in the direction of the arrows.

Figure 5, is an inside elevation taken in the plane of the dotted lines 5--5, Fig. 1,

looking the direction of the arrows.

Figure 6 is an enlarged longitudinal section showing a portion of one of the water distributing pipes broken away.

Figure 7 illustrates a bottom view of a portion of one of the water distributing pipes broken away, and

Figure 8 is an enlarged cross-section of the pipe shown in Fig. 7.

In the embodiment of my invention as illustrated it will be seen that the improved spraying device is suitably mounted upon a truck which is adapted to be moved along on the track rails 1 which are usually installed along the front of and parallel with a series of coke ovens, said truck consisting of the usual wheels 2, axles 3, and longitudinal beams 4E, and as clearly shown, this truck is provided with transversely arranged beams 5, upon the upper face of each of which is suitably mounted a rack 6, and transverse beams 7 upon the upper face of each of which is mounted a suitable track rail 8, for the purpose hereinafter described.

The movable spraying mechanism formed with two upright metallic plates 9 and 10 constituting a part of the supporting frame, and formed integral with the lowermost end of the plate 9 is a lateral extension 10 upon which is suitably mounted an electric motor 11, provided with the usual drive shaft 12 and a driving gear wheel 13 fixedly mounted at the outer end of said shaft. Mounted in the upright frame 13' carried by the extension 10, is a shaft 14 to which is secured a larger gear wheel 15, meshing with said gear wheel 13, and a small gear wheel 16 meshin with a gear wheel 17 mounted on astub-shaft- 18 secured to said frame 13, the latter gear 17, meshing with a gear wheel 18 secured to the shaft 19, said shaft 19 being mounted in the top portion of the upright frame 13, and to the outer end of said shaft 19 is fixedly mounted a gear wheel 20 adapted to mesh with the gear wheel 20 adjustably mounted on a stub shaft 21 within the slotted portion 22 of the upright plate 9, said gear 20 being adapted to mesh with the large gear wheel 22, the latter meshing with the teeth formed on the rack 6, a similar gear wheel 22 being mounted at the other end of the shaft and meshing with the gear teeth on said rack 6. Said shaft 23 and gear wheels 22 and 22 are mounted on the upright frame portions 9 and 10 constituting a supporting medium for the water spraying means, said uprights being connected and braced by the intermediate bars, or beams 24, 24', and a beam 25 fixedly secured to the top portion of the uprights.

Secured to the upper face of the bar 25 is a series of bearings 26, each bearing embracing a water distributing pipe 27 to each of which is removably secured a spraying pipe 28, the inner end portion of each pipe 27 being revolubly secured within the outer end portion of a stationary pipe section 29, each of said pipe sections 29 having a flanged end portion 30 provided with securing bolts 31 and nuts 32 by which each section 29 is fixedly secured to the outer flanged end portion of a pipe 33, each of the pipes 33 being formed integral or connected with what may be termed a larger header pipe 34, to which is suitably connected a manifold water feed pipe 3-3 in communication with said header pipe 34. This header pipe is provided with a plurality of suitable cut-off valves 36, 37, 38 and 39, for the purpose hereinafter described.

It will be perceived that the water spraying pipes are arranged in a series of three distributing pipes for each oven, and as illustrated the device is shown as being adapted to cool the coke in three ovens simultaneously, although it will be understood a more or less number of ovens may be sprayed if desired, by simply lengthening the header pipe and the supply manifold pipe, and it will be seenthat when all of the cut-off valves are closed and the valve 36 is opened one set of three spraying pipes at the right hand side of the device, are caused to spray water over the hot coke, then by opening valve 37, the middle set of three pipes are caused to spray the coke with water and by opening the valves 38 and 39 al of the spraying pipes are caused to spray water into three ovens simulta11eously,hence it isrea-dily obvious that by the proper manipulation of said out off valves any one set of three spraying pipes may be caused to operate separately, or all of them at the of the is fixedly connected with one of the pipes.

27, and rigidly connected with the middle pipe 27, of each series of three pipes 27, is a yoke lever 44, each of said yoke levers having an upward extension 45, the upper end portion of which is pivotally connected with a bar 46, and a lower extension 47, to each of which is pivotally connected one end of a link 48, the other end of each link 48 being pivotally connected to the lower end portion of an arm 49 at the right hand side of each yoke lever 44,- each of said arms being rigidly secured to one of the pipes 27, while near the upper end of the extension of each yoke lever 44 is pivotally connected one end of a link 50, the other end of each link 50 being pivoted to an upwardly extending arm 51 disposed at the left hand side of the yoke lever 44, said arm 51 being rigidly connected to one of the pipes 27; hence it will be readily understood that when motion is imparted to the gearwlieel 40 through the medium of the driving gear adapted to mesh therewith, the rotary movement of said gear wheel 40 will impart to each of the water spraying pipes about a quarter turn or revolution back and forth in opposite directions, through the medium of the links, yokes, arms and bar hereinbefore referred to, thus causing the water to be sprayed regular and continuous through the perforations 52 formed through the bottom portion of each spray pipe without spraying the side walls of the oven.

ll founted on the extension 10 at a right angle to the upright frame 13', is another upright frame 53, and at the upper end of said frame 53 is mounted a shaft 54 having fixedly secured at one end thereof, a friction disk 55, while at the other end of said shaft is tixedly mounted a sprocket wheel 56 to which is connected a suitable endless sprocketchain 57, the other end of said chain being connected to a sprocket wheel 57 suitably keyed to the axle 3 of the truck within the groove or key-way 58 formed within the said axle, as clearly shown in Fig. 3. The shaft 19 is provided with another friction disk 59-which is adapted to be shifted by the friction clutchand lever 60 into contact with the disk 55, which through the medium of the driving means will impart a rotary movement to the sprocket wheel 56 and thus through the chain 57 to the Sprocket wheel 57" whereb the track andits load is caused to be moved along the track to another set of ovens as desired. Then it is desired to move the truck and its load in the opposite direction it is simply necessary to shift the friction disk 59 into contact with the opposite side of the face of the disk 55 by the shifting lever 60, as will be readily understood.

It will be seen by reference to Fig. 5 that a bell-crank lever 61 is pivotally secured to the outer end of the shaft 19, the short arm 62 of said lever being connected with the stub-shaft 21 which carries the gear 20, thus when the motor 11 is started by raising the lever 61 the gear 20 is caused to mesh with the gear wheel 22, thereby causing the spraying mechanism and its frame to be moved transversely over the rack until the said mechanism reaches the desired position with relation to the oven when by pressing downwardly on the lever 61, the gear wheel 20 is immediately shifted into engagement with the gear wheel 10, when a partial revolution back and forth is imparted to the spray pipes 28 by the means hereinbefore described, and the desired spraying operation is performed. When the spraying operation shall, have been satisfactorily completed, it will be simply necessary to shift the driving gear 18, through the medium of the friction clutch and lever 63, into engagement with the gear wheel 15, and shift the gear 20 into contact with the gear 22 by an upward movement of the lever 61, when the driving gear will immediately cause the spraying mechanism to be returned to its initial position, and when it is desired to let the motor run idle it will be simply necessary to shift the driving gear wheel 18 into a position between the gears 15 and 17 by a proper manipulation of the lever 63.

By referring to Figs. 2 and 5 it will be seen that each upright 9 and 10 is provided near the bottom thereof with two small wheels 64, resting upon the tracks 8 and mounted on stub shafts 65 secured to said uprights, said wheels serving as an additional support and guide, in addition to the cog-wheels 22 and 22' engaging with the rack 6, for the spraying mechanism*when it is caused to move into and out from the coke ovens. v

The operation of the device may be briefly described as follows: When the motor has been started in the usual manner and it is desired to feed the spraying mechanism into the coke oven or ovens, and the gear wheel 20 has been shifted by the lever 61 into engagement with the cog wheel 22, the driving mechanism such as clearly shown in Fig. 2, will cause the. spraying mechanism to be moved forwardly along the racks 6 and tracks 8, until it has reached. the desired point with relation to the ovens, when the lever 61 is immediately depressed thereby shifting the gear wheel 20 into engagementwith the gear wheel 40 which will. simultaneously cause a partial rotation of the spraying'pipes back and forth, which operation will be continued until the coke shall have been sufliciently cooled, when by an upward movement of the lever 61, said gear wheel 20 will be shifted into engagement with the cog wheel 22, and simultaneously the gear wheel 18 is shifted by the lever 68 into engagement with the gear wheel 15 which action will cause the spraying mechanism and its supporting frame to be moved in a reverse direction and withdrawn from the ovens, when by the proper manipulation of the lever 60 the friction disks 55 and 59 are caused to engage wit-h each other, thereby causing the truck and its load to be shifted along the track rails 1 by the drive sprockets 56 and 57 and the sprocket chain 57 into the desired position in front of another set of ovens for the purpose of repeating the spraying operation if desired.

It will be understood that a suitable hose is connected at one end to any well known source of water supply, while the other end is suitably connected at 65 with the feed water manifold 35.
